The silanol salts are water-soluble and are characterized in having attached to the silicon atom at least one group comprising a moiety attached to the silicon atom through a substantially non-hydrolyzable silicon-carbon bond and at least one silanol group which is at least partially neutralized with a base. A magnesia composition containing one or more of these organo-silanol salts has improved casting, molding, or spraying properties, as compared to a magnesia composition lacking the silanol salt.
